Researchers from UCLA have developed a terahertz modulator that performs across a wide range of the terahertz band with very high efficiency and signal clarity, which could eventually lead to more advanced medical and security imaging systems. A UCLA Henry Samueli School of Engineering and Applied Science research team has developed a breakthrough broadband modulator […]

The enzyme known as ALOX15 plays a crucial role in the production of anti-inflammatory and pro-resolving lipid mediators. As mammals have evolved, this enzyme has undergone changes to both its structure and function. Researchers from Charité - Universitätsmedizin Berlin have found that human ALOX15 appears to have developed a much higher capacity to stimulate the production of these lipid mediators than the enzyme variant found in lower primates. This discovery might suggest that the

New research led by scientists at The Scripps Research Institute (TSRI) reveals that a human enzyme has changed little from its days as a bacterial enzyme. In fact, the enzyme appears to be unique in its ability to change its shape—and its job in cells—without overhauling its basic architecture.

It has been 20 years since Dolly the sheep was successfully cloned in Scotland, but cloning mammals remains a challenge. A new study by researchers from the U.S. and France of gene expression in developing clones now shows why most cloned embryos likely fail.

Cancer researchers and drug companies may have been too quick to ignore a promising line of inquiry that targets a specific cell protein, according to a research team led by a biomedical scientist in the School of Medicine at the University of California, Riverside.

The recent suicide of Brandy Vela, a teen in Texas City, Texas, was a potent reminder of the sometimes tragic consequences of bullying. According to Vela's parents, the teen fatally shot herself Nov. 29 following months of bullying and sexual harassment, perpetrated in part through text messages and social media.

(Phys.org)—That there are universal patterns in the naming of colors across languages has long been a topic of discussion in a range of disciplines, including anthropology, cognitive science and linguistics. However, previous color term research has not applied an evolutionary framework to the analysis of these worldwide patterns. Recently, scientists at Yale University traced the history of color systems in language by applying phylogenetic methods across a large language tree. They not o

The constellation of Virgo (The Virgin) is especially rich in galaxies, due in part to the presence of a massive and gravitationally-bound collection of over 1300 galaxies called the Virgo Cluster. One particular member of this cosmic community, NGC 4388, is captured in this image, as seen by the NASA/ESA Hubble Space Telescope's Wide Field Camera 3 (WFC3).

The storage of photogenerated electric energy and its release on demand are still among the main obstacles in artificial photosynthesis. One of the most promising, recently identified photocatalytic new materials is inexpensive graphitic carbon nitride. Scientists have now explored a modified form that can produce light-generated electrons and store them for catalytic hydrogen production even after the light has been switched off. They present this biomimetic photosynthesis approach in the journ

As the first 110-footlong wing skin panel for Boeing's new 777X jet moved slowly across a mammoth new factory building one recent morning, a small crew walked alongside, watching for any possibility of an expensive collision.

In a paper published in Acta Cryst. B, Carol Brock of the University of Kentucky looks at some of the organizing principles behind crystal structures with high Z', where Z' is loosely the number of symmetry-independent molecules in the asymmetric unit.

Five million years ago, the Colorado River met the Gulf of California near the present-day desert town of Blythe, California. The evidence, say University of Oregon geologists, is in the sedimentary rocks exposed at the edges of the valley where the river flows today.

The National Institutes of Natural Sciences National Institute for Fusion Science (NIFS) has succeeded in revealing the flow of negative hydrogen ions using a combination of infrared lasers and electrostatic probes in the ion-source plasma, which generates a negative-hydrogen-ion beam. This is the first time in the field of fusion research that the detailed ion flow, which changes direction and moves toward the beam direction in the ion source, has been demonstrated experimentally.

At SciStarter, we aim to make it easy to find and join meaningful citizen science projects. Choose a location, activity, or topic to find appropriate adventures and learn more about the project and what tools (sensors, digital scales, rain gauges, etc) are needed to participate. But, for many projects and would-be participants, there are challenges to accessing the right tools for the job. (We define "tools" as equipment not usually found at home.) So, we took the follow steps to find a solution

Scientists at the University of Bonn have succeeded in observing an important cell protein at work using a method that measures structural changes within complex molecules. The procedure makes it possible to elucidate such processes in the natural environment. The researchers are also providing a tool kit, which allows a wide range of molecules to be measured. Their study has been published in Angewandte Chemie International Edition.

Environmental DNA (eDNA), the nuclear or mitochondrial DNA shed from an organism into its environment, is a rapidly evolving tool for monitoring the distribution of aquatic species. A new study published in Transactions of the American Fisheries Society discusses the ability of eDNA to accurately predict the presence, relative abundance, and biomass of wild Brook Trout (Salvelinus fontinalis) populations.
